Maintenance— 2213 Service
7.
Clean the area around the solder connection with an
approved flux-removing solvent. Be careful not to remove
any of the printed information from the circuit board.
REMOVAL AND REPLACEMENT
INSTRUCTIONS
The exploded view drawings in the “Replaceable
Mechanical Parts” list may be helpful during the removal
and
reinstallation
of
individual
subassemblies
or
components. Circuit board and component locations are
shown in the “Diagrams” section.
Cabinet
W A R N I N G
I
To avoid electric shock, disconnect the instrument
from the ac-power-input source before remvoing or
replacing any com ponent o r assembly.
To remove the instrument cabinet, perform the following
steps:
1.
Disconnect the instrument from its ac-power-input
source.
2.
On instruments with detachable power cords,
disconnect the power cord from the instrument.
3.
Remove the screw from the right rear side of the
cabinet and two screws from the rear panel. Then remove
the rear panel and, if applicable, feed the nondetachable
power cord through the rear panel as the panel is removed.
4.
Pull the front panel and attached chassis forward and
out of the cabinet.
To reinstall the cabinet, perform the following steps:
5.
Slide the chassis frame into the cabinet from the front
until the cabinet is fully into the front-panel groove and the
rear of the cabinet is flush with the rear of the chassis.
6.
Feed the attached power cord (if applicable) through
the hole in the rear panel. Align the rear-panel and side
mounting holes with the screw holes in the chassis frame
and reinstall the three screws removed in step 3.
C A U T I O N
To ensure that the cabinet is grounded to the
instrument chassis, the screw a t the right rear side o f
the cabinet should be tightly secured.
7.
Reconnect the power cord (if disconnected in step 2).
Cathode-Ray Tube
W A R N I N G
I
Use care when handling a crt. Breakage o f the crt
m ay cause high-velocity scattering o f glass fragments
(implosion). Protective clothing and safety glasses
should be worn. Avoid striking the crt on any object
which m ay cause it to crack o r implode. When storing
a crt, either place it in a protective carton o r s et it face
down on a smooth surface in a protected location with
a soft m at under the faceplate.
To remove the crt, perform the following steps:
1.
Disconnect four deflection-plate wires at the middle of
the crt neck and unplug the Trace Rotation connector
(P8006) from the Front-Panel circuit board (note the
connection locations and wire color for reinstallation
reference).
W A R N I N G
I
The crt anode and output term inal o f the High-Voltage
M ultiplier will retain a high-voltage charge a fte r the
instrum ent is turned off. To avoid electrical shock,
ground both the output term inal o f the m ultiplier and
the crt high-voltage anode lead to the main instrument
chassis a fter disconnecting the high-voltage lead.
2.
Unplug the crt anode lead connector from the High-
Voltage Multiplier at the front left comer of the High-Voltage
shield and discharge it to the chassis.
3.
Remove two screws that retain the plastic crt frame
and light filter to the front panel. Remove the crt frame and
light filter from the instrument.
3a. For Instruments with the Preregulator board (A18),
remove two nuts securing the shield at the back of the crt
and remove the shield.
